BMW Introduces New 2010 BMW Z4 sDrive35is - VIDEO
ENHANCED

MUNICH - December 15, 2009: The new BMW Z4 sDrive35is features a modified
straight-six power unit with BMW Twin Turbo Technology and High Precision
Injection, as well as BMW's seven-speed Sport Automatic with double clutch
operation and the M Sports Package including the adaptive M Suspension
likewise featured as standard. Roadster accelerates from a standstill to
100 km/h (62 mph) in just 4.8 seconds. The BMW Z4 sDrive35is is making its
world debut at the 2010 North American International Auto Show (NAIAS) in
Detroit. And parallel to the market launch of this roadster in spring 2010,
the M Sports Package is being introduced for all further versions of the
BMW Z4.

The Top Performer in the Roadster Range

Combining classic proportions with modern sportiness, the new BMW Z4 has reached the top of its
market segment almost overnight. And now this charismatic roadster is entering a new dimension
in driving dynamics, the new BMW Z4 sDrive35is offering an even higher standard of performance
ensured both by the modified straight-six power unit with BMW Twin Turbo Technology and High
Precision Injection, on the one hand, and by BMW’s seven-speed Sport Automatic with double
clutch operation and the M Sports Package including the adaptive M Suspension likewise
featured as standard, on the other. Appropriate optimisation in engine technology increases
maximum output of the 3.0-litre power unit to 250 kW/340 hp. Peak torque is 450 Newton-metres/332 lb-ft,
increasing briefly with the Overboost function to 500 Newton-metres/369 lb-ft. The outstanding power
and performance of the BMW Z4 sDrive35is is expressed in particular by the significant increase
in pulling power and muscle to be clearly experienced in all situations. In conjunction with
seven-speed Sport Automatic featuring double clutch operation, this new top-of-the-range roadster
accelerates from a standstill to 100 km/h (62 mph) in just 4.8 seconds.

At 9.0 litres/100 kilometres (equal to 26.1 mpg US) and 210 grams in the EU test cycle,
fuel consumption and CO2 emissions are the same as on the BMW Z4 sDrive35i with Sport Automatic.

The BMW Z4 sDrive35is is making its world debut at the 2010 North American International
Auto Show (NAIAS) in Detroit. And parallel to the market launch of this high-performance
roadster in spring 2010, the M Sports Package is being introduced for all further versions
of the BMW Z4.

More air, more boost, more torque, more driving pleasure.
The twin-turbo straight-six power unit already giving the BMW Z4 sDrive35i truly impressive
dynamics and all-round performance is characterised in particular by its spontaneous and direct
response to the gas pedal, fascinating free-revving performance, and unusually economical
use of fuel for a car in this class.

Now the outstanding potential of this power unit is being put to even greater use in the new
version of the BMW Roadster, features such as optimised air supply and increased boost
pressure ensuring an even better flow of power with the same high standard of efficiency.

The combination of BMW Twin Turbo Technology and High Precision Injection offers a level
of performance a naturally-aspirated power unit would only be able to provide with a
larger number of cylinders and extra displacement, meaning far higher weight and
significantly greater fuel consumption.

Instead, the BMW Twin Turbo power unit uses two small turbochargers which, through their
low inertia, cut in from the start at relatively low engine speeds, each supplying three
cylinders with compressed air. As a result, power and performance are built up with a level
of spontaneity quite unusual on a turbocharged engine. The turbocharger system developed
for the power unit of the new BMW Z4 sDrive35is maintains a high boost pressure throughout
the entire load range. Peak torque now increased to 450 Newton-metres or 332 lb-ft comes
from a low 1,400 rpm and is maintained consistently all the way to 4,500 rpm. Maximum
output of 250 kW/340 hp, in turn, is delivered at 5,800 rpm.

Overboost function for particularly dynamic acceleration.
Modified engine management on the BMW Z4 sDrive35is also allows the use of an Overboost
function briefly increasing engine torque under full load by another 50 Newton-metres or
37 lb-ft. The peak thus offered of 500 Newton-metres/369 lb-ft gives the car particularly
fast, dynamic and powerful acceleration, the BMW Z4 sDrive35is completing the sprint from
a standstill to 100 km/h (62 mph) in just 4.8 seconds.

Through its particular characteristics, the power unit offers a particularly intense
experience of this supreme performance. The extra output of the optimized
six-cylinder is maintained consistently throughout all load ranges, above all under very
dynamic driving conditions.

When accelerating in the BMW Z4 sDrive35is, the driver feels the additional torque and muscle
particularly at medium and high engine speeds. Following the policy of the BMW Group, finally,
top speed of the BMW Z4 sDrive35is is limited electronically to 250 km/h or 155 mph.
